BIBIBON-INKING ATTACHMENT FOB TYPEWRITERS.

Specification of Letters Patent.

Application filed June 12, 1919. Serial No. 303,722.

T 0 all whom it may concern:

Be it lmown that I, WILLIAM PAIN, a citizen of the United States, residing at Little Rock, in the county .of-Thurston and State of Washin on, have invented certain new and useful mprovements in Ribbon-Inking Attachments for Typewriters, of which the following is a specification.

This invention relates to ribbon-inking devices for typewriting machines; and its object is to produce an efficient device of this character which will be of simple and inexpensive construction, and one which may be readily applied, and will operate automatically. I

To these ends, the invention consists in the novel construction, adaptation and combination of parts as will be hereinafter descrIibei1 and claimed. d

n t e accompanying rawings, Figure 1 is a plan view of my improved ribbon-inker and showing such parts of a typewriting machine necessary to illustrate the application of the invention. Fig. 2 is a sectional view through" 2-2 of Fig.1. Fig. 3 is a perspective view of the casing.

Referring to the drawings, the reference numeral 5 designates part of the machine frame of a typewriter; 6 is the latch; 7 a ribbon-guide one at each side 0 the frame for directing the ribbon R to and from the spools, such as 8, whereby the ribbon is given a progressive feed movement transversely of the machine.

As shown, the ribbon-guide 7 is formed with a straight body portion 9 having adjacent to one end a looped portion 10 which serves to direct the ribbon and extending,

from each side of said looped portion are win guide elements 11.

The aforedescribed parts are similar to devices now employed on standard makes of typewriters-as, for example, that known as Remington.

In carrying out my invention, I provide a receptacle 12 fora liquid absorbent material 13such as sponge-which is detachably connected to the ribbon-guide and is arranged to supply ink to the r1bbon.

Said receptacle is formed with side walls 14, a back wall 15, and a bottom16 which slopes upwardly at the front, as at 16', to within a short distance of a plane extending through the upper edges; of said side walls,

so as to afford an openin or mouth 17, below the cover plate 18. his cover plate is made removable and, by preference, is slidable in guide slots 19 provided in the side walls.

The side walls 14 are, moreover, extended beyond the front edge of the bottom part 16 and are turned inwardly as shown to furnish hook-shaped fingers -20 at opposite sides of the mouth 17 of said receptacle to engage the latter to the looped portion 10 of said ribbon-guide. 21 represent grooves provided in the casing bottom to accommodate the guide el-ments 11 which thereby cooperate with the fingers 20 to prevent any lateral displacement of the casing when in use.

The absorbent material or sponge 13 is placed within the casing and saturated with ink, preferably before the cover plate 'is moved into its closed position, and may be replenished as required by introducing ink through an aperture 23 provided in the cover plate.

In operation, the-ribbon 'in passing over the ribbon-guide 7 is caused to travel'be-= tween the looped portion 10 thereof and a portion of the sponge which protrudes from the mouth of the casing, said looped portion of the ribbon guide serving to retain the ribbon against the sponge, so that ink will be spread uniformly upon the ribbon. Among the advantages of the invention are, first, its efliciency in inking ribbons without the necessity of removin the same from a machine and enabling t eir bein continuously used for a long time or unti worn out; second, in the provision of-a sponge receptacle which is substantially dust proof to exclude dirt from the ink; and third, in the provision of a ribbon inking device which need not be manipulated by the operator of a machine and thereby obviates getting her hands ink soiled.

What I claim, isv p 1. The combination with a typewriter havin a ribbon and a ribbon guide connected to the typewriter, of a casing provided at one end with means for engaging said ribbon guide for securing the casin tothe typewriter, said casing being provided with an opening at one end thereof and at the opposite side of the ribbon from the ribbon guide, and a liquid absorbent material Patented Apr.20, 1920.

provided Within the casing and extending through said opening into juxtaposition with the ribbon.

2. The combination with a ty ewriter having a ribbon and a guide therei or, of a liquid absorbent material, and a casing serving as a receptacle for said material and having a slot at one end through which said material extends, said casing being pro- 10 vided with fingers at opposite sldes of said slot to engage the ribbon ide forsecuring the casing thereto in position to cause the.
